Claims

[Scope of utility model registration request]

A discharge port is provided on the sealed end plate of either the fixed scroll member or the movable scroll member, and when this discharge port and one sealed small chamber communicate with each other, the other sealed small chamber and the discharge port are provided on the other sealed end plate. A scroll-type fluid machine characterized in that the pressure between the two closed chambers is balanced by communicating with each other through a provided pocket.
